Sine jaw

ABSTRACT

MY INVENTION IS A MACHINE VISE JAW, MODIFIED WITH 0.063″ HOLES, TO ACCEPT {fraction (1/16)} DOWEL PINS TO PROVIDE THE MACHINIST EASY SET UP TO MACHINE ANGLES IN AN “KURT ANGLE LOCK VISE”.

[0001] MY INVENTION IS A MACHINE VISE JAW MODIFIED WITH 0.063″ HOLES TOACCEPT {fraction (1/16)}″ DOWEL PINS TO PROVIDE THE MACHINIST EASY SETUP TO MACHINE ANGLES IN AN “KURT ANGLE LOCK VISE” TWO 0.063″ HOLES AREDRILLED FOR TWO PIVOT HOLES. A 1.75″ RADIUS CENTERED ON EACH PIVOT WITH0.063″ HOLES IN 5 DEGREE INCREMENTS RADIALLY. THEY ARE ENGRAVED WITHNUMBERS TO TELL THE ANGLES THEY REPRESENT.

[0002] THE BOTTOM SET, IS TO MACHINE SMALLER ANGLES SO THE PARTS WILLSIT LOWER IN THE VISE AND HAVE MORE HOLDING AREA

[0003] SEE (drawings page 4).

[0004] THERE ARE 12 ANGLE BARS FOR VARIOUS ANGLES, RANGING FROM 30MINUTE

[0005] TO 90 DEGREES IN 30 MINUTE STEPS (see drawings page 5 and 6).

[0006] FOR A DEMONSTRATON OF HOW TO MACHINE BLOCKS (see drawing page 7).

[0007] RELATED ITEMS (see drawings page 8, 9, 10, 11 and 12).

What I claim:
 1. I AM A RETIRED MACHINIST. I HAVE WORKED IN MACHINESHOPS FOR OVER 40 YEARS. IN THAT TIME HAVE SPENT THOUSANDS OF HOURSLOOKING FOR PARALLELS, THAT ARE PAIRS AND THE RIGHT HEIGHT, LOOKING FORVISE STOPS, AND SPRINGS TO KEEP THE PARALLELS APART. I SAID TO MYSELFTHERE MUST BE A EASIER WAY, SO I DESIGNED THIS MULTIPURPOSE VISE JAW.THIS IS USED ON VERTICAL MILLING MACHINES. “KURT ANGLE LOCK VISES”. ICALL IT A SINE/JAW AND IT USES SMALL ANGLE/BARS. SEE LIST OF SEVENDRAWINGS FOR EXPLANTIONS ON HOW THEY WORK.
